Exercise should be ‘core treatment’ for depression – study (www.standard.co.uk)

Exercise should be a “core treatment” for people with depression, academics have said, after a new study suggested that some forms of exercise were just as good as therapy and even better than anti-depressants.

Walking, jogging, yoga and strength training appeared to be more effective than other types of exercises, according to a major new analysis.

And the more vigorous the exercise, the better, according to a research team led by academics in Australia.

But even low intensity exercises such as walking and yoga had meaningful benefit.

The effect of exercise appeared superior to antidepressants, according to the study which has been published in The BMJ.

But when exercise was combined with antidepressants, this improved the effect of the drugs.

Since the study wasn’t actually linked (as far as I can tell on mobile), here’s a link to it.

From the conclusion: “Depression imposes a considerable global burden. Many exercise modalities appear to be effective treatments, particularly walking or jogging, strength training, and yoga, but confidence in many of the findings was low”

I always worry about studies like this because it always seems to me like it might be difficult to determine if exercise is the catalyst to better mental health or if someone’s bettering mental health through any number of other kinds of treatments or even changes in a persons social life was the catalyst for exercising more. When I’m feeling particularly depressed, I absolutely don’t feel like exercising, and when I start to feel hopeful for the future, I find myself wanting to exercise more. Same with “just go outside and walk through the woods”. I only feel like doing that on days my depression isn’t particularly bad.

Thanks for the link.

I think the authors shared your concern as well.

Our review did not uncover clear causal mechanisms, but the trends in the data are useful for generating hypotheses. It is unlikely that any single causal mechanism explains all the findings in the review. Instead, we hypothesise that a combination of social interaction,61 mindfulness or experiential acceptance,62 increased self-efficacy,33 immersion in green spaces,63 neurobiological mechanisms,64 and acute positive affect65 combine to generate outcomes. Meta-analyses have found each of these factors to be associated with decreases in depressive symptoms, but no single treatment covers all mechanisms.
